+This tests the support for the bigarray atom in the dune libraries stanza.
+
+History:
+- OCaml 4.05 ([ocaml/ocaml#997](https://github.com/ocaml/ocaml/pull/997) and
+[ocaml/ocaml#1077](https://github.com/ocaml/ocaml/pull/1077)) add
+`Unix.map_file` allowing the `map_file` functions in `Bigarray` to be
+deprecated. Bigarray remains a separate library.
+- OCaml 4.07 ([ocaml/ocaml#1685](https://github.com/ocaml/ocaml/pull/1685))
+adds `Stdlib.Bigarray`, but without the `map_file` functions (since these
+required `Unix.file_descr`. The separate library remains with those
+functions (but still marked as deprecated). Code can be updated to use
+Unix.map_file and then Stdlib.Bigarray and not require the separate library
+at all, but the separate remains compatible with OCaml 4.06.
+- OCaml 4.08 ([ocaml/ocaml#2263](https://github.com/ocaml/ocaml/pull/2263))
+deletes the `map_file` functions completely, requiring _all_ code to be
+updated to use `Unix.map_file`, if appropriate. From this release, it is
+unnecessary to link with the separate Bigarray library.
+- OCaml 5.00 ([ocaml/ocaml#10896](https://github.com/ocaml/ocaml/pull/10896)
+removes the separate Bigarray library.
+
+Code may be written which is designed to support both OCaml 4.06 and earlier and
+also OCaml 5.0+. In such cases, it is appropriate to have `(libraries bigarray)`
+even though there is no Bigarray library in OCaml 5.
+
+This test uses `(libraries bigarray)` (the program uses `Bigarray`)
+  $ dune exec a/a.exe
+  Welcome to a
+This test uses `(libraries (re_export bigarray))` similarly
+  $ dune exec b/b.exe
+  Welcome to b
+This test uses a `(select )` construct and should always select bigarray support
+  $ dune exec c/c.exe
+  Welcome to c WITH bigarray support
